Controls Reduce Security Threats
Technology is only a part of the measures it takes to produce a strong, secure information system. Well written security policies can lay the ground work and tell employees what is mandated and required to protect the information system. Remote access should be a part of the security policy to control who does what and what they are allowed to access in the system. Setting standards for the types of devices that are allowed to access the system is equally important.
"Without an effective security policy that addresses procedures, mitigation strategies, and periodic training, all other security programs will be less successful." (Welander, 2007) Technology alone will not protect the information system of the business. Employees need to be trained on the security standards that are set for the company. No matter how secure the system is, employees can let intruders in just by checking personal email or exploring the internet on breaks.
"Controlling...
Only management employees should have access to allow someone to enter the system and control what they are allowed to do. With management controlling the access, responsibility is placed where it should be without letting others access something they do not need to do the job.
The security policy should address network login with usernames. Passwords should have minimum and maximum length, be complex, and should be changed periodically. Remote access should designate who is allowed to access and do what. What are the system requirements? What software and applications will be allowed? The internet connections need to be explained in the policy. How are computers tracked? How is equipment and media disposed considering harmful effects? How should media be allowed to be used and stored in the system?…

The reality is however that legacy systems pose the greatest potential risk to any enterprise, as these platforms are anachronistic in terms of security support, lack many common safeguards, and don't have the necessary Application Programmer Interfaces (APIs) to scale globally as a secured platform (Gupta, Roth, 2007). Legacy systems were designed in an era where single authentication for an entire enterprise system was sufficient enough, and the concept

Security Management The role of a security manager varies widely according to the particular organization and its needs, but despite this variety, there remain certain best practices and policies that can help maintain security and stability. This is nowhere more true than in the case of organizational loss, because while loss can mean widely different things depending on the field, the underlying theoretical concepts which inform attempts to minimize loss are
To offer an information security awareness training curriculum framework to promote consistency across government (15). Security awareness is needed to ensure the overall security of the information infrastructure. Security awareness programs is the can help organizations communicate their security information policies, as well as tips for users, to help keep systems secure, and the practices the entire organization should be utilizing. However, as Kolb and Abdullah reiterate, "security awareness is not
They need to know what their responsibilities are not only as individuals but also as team members and corporate employees. David cites an excerpt from a corporate security document that illustrates his point: "A security policy serves many functions. It is a central document that describes in detail acceptable network activity and penalties for misuse. A security policy also provides a forum for identifying and clarifying security goals and
This researcher rejects the existence of online communities because computer mediated group discussions cannot possibly meet this definition. Weinreich's view is that anyone with even a basic knowledge of sociology understands that information exchange in no way constitutes a community. For a cyber-place with an associated computer mediated group to be labeled as a virtual settlement it is necessary for it to meet a minimum set of conditions. These are:
